1. ARTIFICIAL NEURAL NETWORKS FOR PREDICTION OF PHYSIOLOGICAL AND PRODUCTIVE VARIABLES OF BROILERS
ABSTRACT Due to a number of factors involving the thermal environment of a broiler cutting installation and its interaction with the physiological and productive responses of birds, artificial intelligence has been shown to be an interesting methodology to assist in the decision-making process. For this reason, the main aim of this work was to develop an art

2. Lamina specific loss of inhibition may lead to distinct neuropathic manifestations: a computational modeling approach
Introduction It has been reported that inhibitory control at the superficial dorsal horn (SDH) can act in a regionally distinct manner, which suggests that regionally specific subpopulations of SDH inhibitory neurons may prevent one specific neuropathic condition. Methods In an attempt to address this issue, we provide an alternative approach by integrating

3. Neural regulation of the stress response: glucocorticoid feedback mechanisms
The mammalian stress response is an integrated physiological and psychological reaction to real or perceived adversity. Glucocorticoids are an important component of this response, acting to redistribute energy resources to both optimize survival in the face of challenge and to restore homeostasis after the immediate challenge has subsided. Release of glucoc

4. Proposta e avaliação de um modelo computacional de gerador central de padrões / Proposal and evaluation of a computational model of Central Pattern Generator
The concept of Central Pattern Generator-CPG can be described as neural network capable of producing coordinated rhythmic locomotor activity apart from any external rhythm or sensorial stimuli. As this group of neurons are autonomic and are located in the spinal medulla, is experimentally observed that brainless animal‟s exhibit robotized locomotor act

6. Avaliação do desenvolvimento de girassol por meio de analise de proteinas e metaloproteinas / Evaluation of sunflower development based on protein metalloprotein analysis
This work describes an evaluation of sunflower (Helianthus annuus L.) growth when it is submitted to seven treatments, and their interrelation with proteins and metalloproteins analyses. Metal ion solutions (Cd, Cu, Pb and Zn) were added to the substrate in four treatments. In another two, used as controls, the plants were irrigated only with deionized water

7. Mutation of the proto-oncogene c-kit blocks development of interstitial cells and electrical rhythmicity in murine intestine.
1. Interstitial cells of Cajal (ICs) have been proposed as pacemakers in the gastrointestinal tract. We studied the characteristics and distribution of ICs and electrical activity of small intestinal muscles from mice with mutations at the dominant-white spotting/c-kit (W) locus because the tyrosine kinase function of c-kit may be important in the developmen

8. Linear information processing in the retina: a study of horizontal cell responses.
A basic question about visual perception is whether the retina produces a faithful or a distorted neural representation of the visual image. It is now well known that in some retinal pathways there are significant nonlinear transductions which distort the neural image. The next natural question is, What are the locations of the nonlinear stages within the re

9. Frontostriatal deficits in fragile X syndrome: Relation to FMR1 gene expression
Fragile X syndrome (fraX) is the most common known cause of inherited developmental disability. fraX is associated with a CGG expansion in the FMR1 gene on the long arm of the X chromosome. Behavioral deficits, including problems with impulse control and distractibility, are common in fraX. We used functional brain imaging with a Go/NoGo task to examine the

10. Cells and circuits contributing to functional properties in area V1 of macaque monkey cerebral cortex: bases for neuroanatomically realistic models.
Anatomical and physiological data obtained from investigations of area V1 of the macaque monkey visual cerebral cortex have been used in 3 models outlining possible circuitry underlying functional properties of the region. The 3 models use, respectively, a fully implemented computer neural network, a mathematical formulation of interactions in a descriptive

11. Enhanced cocaine responsiveness and impaired motor coordination in metabotropic glutamate receptor subtype 2 knockout mice
Extensive pharmacological studies have recently emerged indicating that group 2 metabotropic glutamate receptors (mGluRs) comprising mGluR2 and mGluR3 subtypes are associated with several neurological and psychiatric disorders. mGluR2 is widely distributed both presynaptically and postsynaptically in a variety of neuronal cells, but the physiological role of

12. Scopolamine Enhances Generalization between Odor Representations in Rat Olfactory Cortex
Acetylcholine (ACh) has a critical, modulatory role in plasticity in many sensory systems. In the rat olfactory system, both behavioral and physiological data indicate that ACh may be required for normal odor memory and synaptic plasticity. Based on these data, neural network models have hypothesized that ACh muscarinic receptors reduce interference between
